Add new output type

Write a new package to implement the interface output.Output:

type Output interface {
    Save(nodes *runtime.Nodes)
}

Save a pre-filtered state of the Nodes

For startup, you need to bind your output type by calling output.RegisterAdapter("typeofoutput",Register)

it should be in the func init() {} of your package.

The typeofoutput is used as mapping in the configuration [[nodes.output.typeofoutput]] the map[string]interface{} of the content are parsed to the Register and on of your implemented Output or a error is needed as result.

Short: the function signature of Register should be func Register(configuration map[string]interface{}) (Output, error)

At last add you import string to compile the your database as well in this all package.
